The present study classified groups based on latent profile of self-determination motivation(amotivation, external motivation, intrinsic motivation), and examined the determinants for each group. The data was collected through panel data of Korea Education Longitudinal Study(KELS), total 5,459 participants who answered questionnaires of self-determination motivation of two times both second grade of middle school and second grade of high school. To identify the change motivational type, standardized residual was conducted using SPSS 17.0., and the latent classes for the change of motivational type was investigated using M-Plus in the frame work of Latent Profile Analysis(LPA). The results indicated that five groups(increase of self-determination, self-determination maintenance, self-determination developmental delay, elf-determination confusion, decrease of self-determination group) were classified based on latent profile. In addition, parental control, academic self-concept, teacher-student relationship, test anxiety, avoidance orientation, gender, father's education, and income were significantly related to each group. Lastly, the implications for directions of the adolescent counseling, limitations and future research are discussed.

Prior researches on Internet shopping have focused on cognitive, technological factors, but this research is focused on emotions experienced during internet shopping. Examines emotion types experienced during internet shopping and shopping mall characteristics influencing emotional response and effect of emotions on internet shopping behavior, specifically focusing on shopping motivation difference. The data, collected from a sample of 323 internet shoppers, indicate that emotion types experienced during internet shopping and shopping mall characteristics influencing emotional response and emotional response influencing internet shopping behavior are difference among shopping motivation. Theses results provide insights on internet shopping mall management according to shopping motivation.

This study investigated cyber university students' motivation and demotivation in learning English. Data was collected from a survey of 498 students in a general English course at a cyber university located in Seoul. The survey inquired into participants' English learning motivation and demotivation. To analyze the data, frequency analysis, descriptive statistics, t-test, and ANOVA were used. The findings reveal that among the motivation factors ideal L2 self was the main cause of motivation followed by promotion-based instrumentality. Among the demotivation factors the anxiety factor was found to have the highest mean followed by negative investment value for learning English. The statistical analysis of English learning motivation and demotivation according to the participants' characteristics indicates that, in terms of English learning motivation factors, the male participants' ought-to L2 self was significantly higher than that of the females' and the promotion-based instrumentality of the students who are unemployed was higher than those who are employed. Moreover, the younger the students' age, the higher their competitive motivation and promotion-based instrumentality. In terms of English learning demotivation, the female respondents achieved higher scores in the factors of anxiety, passive learning style, and negative investment value for learning English than their male counterparts. In addition, employed students showed higher demotivation in negative investment value for learning English than those without employment. The findings of this research can be used in developing online English programs for cyber university students who possess diverse learning goals.

This study examined the effects of procedural justice on two facets of OCB (OCBI and OCBO) in local public enterprises and the mediating role of intrinsic motivation in these relationships. We verified the hypothesis established by a structural equation model based on PLS. The research data were collected through a survey of 269 employees working for local public enterprises. Research has shown that procedural fairness has a positive effect on intrinsic motivation, organizational citizenship behavior directed at individuals (OCBI), and organizational citizenship behavior directed at the organization (OCBO), while intrinsic motivation has a positive effect on OCBI and OCBO. In addition, intrinsic motivation has been found to have a partial mediating effect in the procedural justice-OCBI relationship and the procedural justice-OCBO relationship respectively. Finally, we present theoretical and practical implications that organizations need to activate intrinsic motivation so that members can induce voluntary organizational civic action through improved procedural fairness.

This study attempted to identify various variables that affect satisfaction and continued use intention of the subscription economy services. Through previous research studies, individual characteristics and service characteristic variables were considered together. Finally, use motivation, platform characteristic factors, and product and service characteristic factors were classified and examined. As a result of the study, the motive for using the service that affects the satisfaction of the subscription economy service was found to be functional hedonic, and economic motive, and platform recency and convenience, economic utility, and perceived personalization had a positive effect. Functional and hedonic motives and convenience showed positive influences on continued use intention, while social motives showed negative influences. In addition, it was confirmed that economic motivation, platform recency, economic utility, and perceived personalization showed a positive influence on the intention to continued use intention by mediating satisfaction with subscription economy services.

Grit, defined as "perseverance and passion for long-term goals", is a known personality trait that successfully predicts high performance in various fields. In spite of extant evidence of the effectiveness of grit, research has not yet clarified the relationship between grit and conscientiousness, a highly correlated personality trait. In this study(N = 355), we examined the effect of grit and conscientiousness on academic achievement, mediated by self-determination motivation. As a result, grit and conscientiousness both predicted academic performance, and intrinsic motivation mediated these relationships. However, conscientiousness no longer related with motivation and academic achievement when grit was controlled for, whereas grit maintained its relationship with motivation and achievement even when conscientiousness was controlled. This result indicates that although the two psychological concepts overlap to some extent, grit has a unique motivational and behavioral effect that distinguishes it from conscientiousness. The present study expands the current understanding of grit with its comparison between grit and conscientiousness. We suggest future research ought refine the grit scale to establish its discriminant validity.

This paper presents an automatic frequency control algorithm for RTLS DS-SS modem based on the standard of ISO/IEC 24730-2. The presented automatic frequency control algorithm consists of frequency acquisition mode and frequency tracking mode, and the frequency acquisition mode is divided into the angle estimation step for frequency offset estimation and the verification step for removing the angle ambiguity. In the angle estimation step, three different sub-bit angles are estimated according to the timing intervals, then the estimates are used to re move the angle ambiguity in the verification step. The theoretical analysis and the simulation results of the proposed frequency control algorithm are presented.

Some process algebras were applied to enterprise business modelling for formal specification and verification. ${\pi}$-calculus and mobile ambient can be considered for the distributed and mobile, especially to represent the movements of distributed real-time business processes. However there are some limitations to model the movements: 1) ${\pi}$-calculus passes the name of port for indirect movements, and 2) mobile ambient uses ambient to synchronize asynchronous movements forcefully. As a solution to the limitations, this paper presents a new process algebra, called ${\delta}$-calculus, to specify direct and synchronous movements of business processes over geo-temporal space. Any violation of safety or security of the systems caused by the movements can be indicated by the properties of the movements: synchrony, priority and deadline. A tool, called SAVE, was developed on ADOxx metamodelling platform to demonstrate the concept.
